Title: Iron-core type reactor provided with gap
Inventor: HAMADATE YOSHIO
IPC: H01F27/24
Filed: 1989-05-26
Abstract: PURPOSE:To prevent a yoke iron core from being heated locally without increasing a block iron core and taking measures against a slit by a method wherein a distance between the block iron core and the yoke iron core is made larger as it is situated at an outside end part where they face each other. CONSTITUTION:A part where a block iron core 1 and a yoke iron core 4 which is arranged at its upper part is faced is shaved off partially so as to form a structure that they are arranged on a tripod. Since a distance is separated as it is situated at an end part of the iron core 1 and the iron core 4, a leakage flux phi from the iron core 1 is not leaked to the surface of the iron core 4 and can be attracted to the inside of the yoke iron core 4; the flux in large quantities penetrates into end faces of a silicon steel belt. As a result, it is possible to prevent the yoke iron core 4 from being heated locally.

Abstract: PURPOSE:To provide a stable combustion having a low noise and having a tendency of producing less soot regardless of premixing or dispersion type combustion by a method wherein a porous cylindrical nozzle for fuel having several nozzle fine holes at an extremity end thereof is arranged at a central part within a cylindrical combustion chamber and a rotating vane is arranged between a base part of the porous nozzle and an inner wall of the combustion chamber. CONSTITUTION:Fuel passes through a fuel pipe 3 and is injected from a central part and a circumference of a porous nozzle 2 having several nozzle small holes 2a at an extremity end thereof into a combustion chamber 1. At this time, air flowing within the combustion chamber 1 may form a circulating flow by a rotating vane 6 and flows to a downstream end of the combustion chamber 1 while winding the porous nozzle 2. Fuel injected from above the circumference of the porous nozzle 2 and the rotating air are struck against to each other to promote a dispersion type mixing operation. Then, the fuel and air may form a cylindrical flame and a premixing area so as to cover the porous nozzle 2 and then a flame is also formed from the extremity end of the nozzle 2. In this way, a cylindrical flame having a high uniform state due to a high-speed dispersion and a rotating flame at a downstream side of the porous nozzle are formed and then a combustion producing less soot can be continued over a wide range without having any relation with the premixing and dispersion type combustion.

Title: Injection speed controlling device of injection molder
Inventor: YAMAMOTO NAOKI
IPC: B29C45/50
Filed: 1997-05-22
Abstract: PROBLEM TO BE SOLVED: To easily obtain the controlling conditions of an injection speed optimum for a new injection mold by a method wherein the amount of deviation of a detected pressure from a reference pressure is calculated so as to obtain the correction value of the injection speed on the basis of the amount of deviation and the injection speed at the time when the detected pressure exceeds the reference pressure by means of proportional integral calculation or proportional integral differential calculation. SOLUTION: In order to obtain the correction value of an injection speed, which brings the difference between the pressure of molten material detected during its transfer in an injection screw 30 to null, through calculation, first of all, the amount of deviation of the pressure from a reference pressure is obtained. Then, the correction value of the injection speed is obtained on the basis of this amount of deviation and the injection speed at the time when the detected pressure exceeds the reference pressure by means of proportional integral (henceforth expressed as PI) calculation or proportional integral differential (henceforth expressed as PID) calculation. As a result, an injection speed, which is corrected in response to the rise rate of the detected pressure, which becomes larger than the reference pressure, of the molten material, can be obtained.  Consequently, the amount deviated from the reference pressure of the detected pressure realized by the corrected injection pressure can be made smaller.
